I'm aware of lipohypertrophy. Please remember that I'd been injecting for
almost 3 decades. I'd developed fatty deposits at every injection site --
arms, abdomen, buttocks and thighs. These deposits were not particularly
pretty to look at, but they never interfered with insulin absorption. Since
I rigorously followed site rotation techniques, there was nothing I could
do about them, either. Now that I''m no longer using my arms, buttocks, or
thighs for injections, all the lumps in these locations have completely
The new fat deposits on my abdomen are more substantial and less lumpy.

Well, that depends on what "eventually" means. If someone offered me, say,
several years of effortless infusion set use in return for a later risk of
absorption problems, I'd take that risk every time. After all, if the
alternative meant that I'd use infusion sites that never developed such
protective layers, I'd leave myself open to the risk of discomfort from
site infections, since that's what I initially experienced using the same
technique. IAC, at this point, absorption is not a problem. In fact,
insulin administration has never ever been easier.
What's interesting, moreover, is that although lipohypertrophy is listed as
interfering with absorption, it is *not* listed as beneficial for cannula
tolerance. How come? Is my hypothesis concerning such a beneficial effect
incorrect? Alternatively, are we perhaps referring to two different things?
